Convert byte value to character value

Declaration

Source position: systemh.inc line 1119

function chr(

  b: Byte

):Char;

Description

Chr returns the character which has ASCII value X.

Historical note:

Originally, Pascal did not have typecasts and chr was a necessary function in order to do certain operations on ASCII values of characters. With the arrival of typecasting a generic approach became possible, making chr mostly obselete. However, chr is not considered deprecated and remains in wide use today.

Errors

None.
